Question

Which of the following is the greatest? A) 4.3 B) 4.0004 C) 4.02 or D) 4.0009

Answer 1

The correct answer to this question is A) 4.3.

When we are comparing numbers and their value, we start by comparing the number farthest to the left. All of the answer choices start with the number 4 and this are equivalent in this place, so then we move one place value to the right (in this case, on the other side of the decimal point). Answer A has a 3 in this place, whereas the other options have a 0. Because 3 is greater than 0, we can conclude that answer A is greater than the other options.

Hope this helps!

Answer 2

A) 4.3 is your answer.

Note that for place values after the decimal point (.), the numbers towards the left that are greater signifies that the number (if the whole numbers are the same) is greater than the others.

For example, 4.3 is greater than 4.02 by 0.28.
